RADIATOR.

SPECIFICATION forming part of Letters Patent No. 421,042, dated February 11, 1890.

Application filed June 5, 1889.

To a/ZZ whom, it may concern:

Beit known that I, Lmlvinaxcn R. BLACK- MORE, a citizen of the United States, residing at Newark, Essex county, New Jersey, have invented certain new. and useful Improvements in lIeating-Rznliators, fully described and represented in thefollowing spceileatien .and the accompanying drawing, forming a Vpart of the saine.

" nicnts in radiators hereinafter set forth.

This invention consists in the improve- In the annexed drawings, Figure l is a plan, Fig'. 2 a transverse section, and lfig. il an elevation in section where hatched, of. a radiator constructed with in y improvements. Fig. 4 is a transverse section, Fig. 5 a plan, and liig. G a transverse section taken at right angles to that shown in Fig. l, ol` the inlet-valve. Fig. 7 is a plan, and Fig. S a transverse section, of the lloor-plate to which the supply-pim is attached. Fig. J is a central longitudinalsection oi' the air-valve.

The grated cover customarily applied to the tops of radiatorsl ot this class is omitted from the drawings, as itsI use is already well known.

The radiator shown herein comprises a series of itat horizontal sections u, each having its ends er heads connected by narrow water-spaces l), separated byvertieal longitudinal slots c, the'latter being provided in order to permit the l'ree eireulationof airadjacent to the heating-surl'aees, as in other constructions heretofore in use. The sections are connected together alternately attheir opposite ends by nipples y, and are provided at their other ends with lugs o, to hold their surfaces apart, su as lonllow lhel'ree jzassage of air between them.

In radiators oi' this class it has been found desirable to connect the supply-pipe direetl y with the upper section and the outlet-pipe with-the lower section. lo el'lect this object without disguring the radiator by the application of an external vertical pipe, 1 foi-1n each ot the sections below the top one with transverse sockets c near the ends and project the vertical supply-pipe s through the saine to the top section at one end of the radiator. 1 `or convenience in casting the sepa ate sections to be united at their alternate Serin No. 313.146. (Nt model.)

ends both the heads are shown formed with the sockets e, although the socket at one end only is utilized when the section is conneet-ed.

In lfig. d the supply-pipe .s is shown cxtended from the iloor up through the sockets in the several sections to the under side of the top section; where it is connected with a thiinble f/, having a valve-seat formed upon its upper face and provided witha slidevalve j, having a rod Z extended outside of the section from a stuffing-box m. Beveled guides en. force the valve down on a packing l in the seat. A recess n is cut in the sloping face at the underside ol' thesection where the valve-stem projects, so as to pel-init the application ol` ille stu'ling-'box where it would be eoveret'l by the ,edge of the section, and thus both the valve and the means for operating the same are concealed by the upper section to which they are applied. It is obvious that the sections must be alternately reversed in eonjfleeting them on top ol one another, so as tobring thea-pertures lorthe nipples in a suitable. position, which reversal otv the sections in building the radiator involvesI the formation el' the sockets c at both ends of each section, so as to provide a emitinuous aperture through the sections when superposed for the sup1 ily-pipe s. '.lo conceal the air-valve r from view, it is constructed to lt wholly within -the radiatorsection, being attached te a shank yn ol sulicient size lo permit the passage oi' the airvalve through the thremled hole-into which the shank is screwed, as shown in Eig. 3. '.lhe shank is formed with a recess 1o in its outer end, in which the stem nf" ot` the valve is inelosed, and in which a key may In: inserted to adjust the' valve when required, as shown in Eig. 9. The inner neck ol.' the airvalve is heut at rightauglestotheshank, and is thus adapted by suitably turning'theshank to project up to the highest point. within the .rat'liateia 'lhe introduction of such bent neck o is effected by making the |sa'me eonsiderably smaller tha'n the shank, so that it can be introduced. through theihreiuled hole inthe upper section to which the shank is fitted.
